Heretofore the hammer, including frame Referring to the construction ofhead-block and striker, represented at 6 and of the ordiattached to theextensions, such head-block is 5 nary steam-operated type, has been sodemade of two parallel I-beams 11, upon which signed as to slide up anddown between the are mounted the bearings 12 for the pulleys I 5permanent leaders by having guides formed or sheaves 10. These beamsrest upon and thereon, so as to directly engage the sides of are securedto angle-plates 13, such plates bethe leaders. In the present instanceinstead ing in turn secured to the extensions.

In the instance of the modified form of construction the head-block isbuilt up of two parallel I-beams 11 and two transverse 1- beams 11, uponwhich are mounted the bearings 12 for the pulleys or sheaves 10hereinbefore referred to. The flanges of the beams 11 are provided nearopposite ends with an outer and inner series or set of holes 14: and 15,respectively, the outer set 14 being arranged to receive dowel-pins l6,projecting upwardly from the top of the permanent leaders, and the innerset 15 being arranged to receive similar pins 17, projecting upwardly inlike manner from the top of the extensions, all as clearly illustratedin Figs. 5 and 6.

When the head-block is resting upon the top of the leaders, Fig. 6, andthe extensions are in their lowered position, the holes 14 of suchhead-block are engaged by their pins 16. When the extensions are raisedin the manner hereinafter explained, their pins 17, which normallyrested below the head-block in inoperative position, as indicated inFig. 6, enter the holes 15 of the head-block, so that the latter iscentered and secured upon the extensions. Continued elevation of theextension carries the head-block upwardly, inasmuch as it has beentransferred to the extensions and becomes aflixed thereto in the mannerdescribed. The head-block now performs on the extensions the samefunctions which it performed upon the permanent leaders.

When the extensions are lowered, the headblock will of course descendwith them and eventually take its place upon the leaders, to which it isthus automatically retransferred and secured against lateraldisplacement.

The pulleys or sheaves 1O cooperate with the rope or cable 18, whichpasses over the pulley or sheave 19, journaled to the hammer at thecylinder end thereof, Figs. 1 and 1, and which extends downwardly to thehoisting-drums in the usual manner that requires no description. Toproperly deflect and guide the hoisting rope or cable, I provide apulley 20, which is secured to the inner one of two side plates 21,which are riveted to the extensions at the top thereof, and therebyconnect their flanges, as clearly illustrated in Figs. 2 and 8.

Toward its upper end, Fig. 1, each of the leaders has aslot23, in whichis journaledasheave 24:, as illustrated in detail in Fig. 7. Suchsheaves may be located at any desired position along the length of theleaders, even, in fact, on top thereof. Each leader in the presentinstance has on its inner side toward the extensions and below thesheave 2 1 a vertical or longitudinal groove or channel 25 toaccommodate a rope or cable 26, which is fastened toward the lower endof the extensions or at any intermediate point by means of theclamping-plate 27, riveted or otherwise secured to the extension andclamping the end of the cable 26. The two ropes or cables 26 extenddownward, as seen in Fig; 1, and are connected to the w1nding orhoisting drums of the engine, w1th the result that the extensions may beelevated to the desired height.

The extensions may be of any desired length, either of the same lengthas the permanent leaders or longer or shorter than the latter. Theleaders and extensions are arranged to telescope, and the same may alsobe folded in the well-known manner, with the result that the entiremachine may be folded in small compass for transportation purposes,requiring only one car instead of two if transported on the railway.

When the driver is of the steam-hammer type, the so-called hammer, buttechnically the frame thereof, is provided with opposite verticalprojections or lugs, as described, which slide in the inner adjacentchannels of the 1-beam extensions. hen these extensions are lowered tobe within the lines or compass of the leaders as well as when theextensions are raised, these channels form the guide for the hammer, andas matter of fact these I- beams may be used as a part of the leadersand their function as extensions be dispensed with, whereby a mostefficient and reliable machine would result. However, in case such beamsshould thus be employed as the leaders in effect they may be simplechannel-beams secured in suitable manner to the ordinaryleaders, or suchleaders may be dispensed with. In Fig. 10 I have shown such beams 8 withsufficient flange for securing them to the leaders by bolts 8", althoughplain channelbeams may be used if the same are otherwise secured to theleaders when the latter are employed.

As hereinbefore stated, my invention is applicable to pile-drivers ofthe drop-hammer type; but in such case the hammer instead of having thevertical corner-flanges has two opposite lugs or projections, as shownin Fig. 9, in which 28 represents the hammer and 29 the lugs, These lugstravel in the channels of the I-beams in the same manner as the lugs ofthe hammer-frame of the steam-hammer type of driver.

Inasmuch as my invention is applicable to both the steam and drop hammertypes of pile-drivers, as hereinbefore made apparent, it will beunderstood that when a hammer is mentioned in the claims I refer toeither one of such types thereof. Also that so far as some of the claimsare concerned the beams are not necessarily to be understood asextensions, for the reason, as already stated, that such beams may bealways within the length or compass of the permanent leaders, which may,in fact, be dispensed with when the function of extension of the beamsis not required.
